AMBULATORY CARE:
Rheumatic fever
is a condition that develops when a group A strep (GAS) bacterial infection is not fully treated. A GAS infection can cause strep throat, scarlet fever, and impetigo. Rheumatic fever is an autoimmune condition. This means your child's immune system overreacts to the bacteria and attacks healthy tissues. Inflammation forms in your child's joints, nerves, heart, and brain. Anyone can develop rheumatic fever, but it is most common in children 5 to 15 years old.
Signs and symptoms of rheumatic fever
may start 1 to 5 weeks after a GAS infection:
- A rash that has pink rings and a clear center
- Swollen joints, usually in the knees, ankles, elbows, and wrists
- Lumps near the affected joints
- Body movements that are not controlled or are jerky
- Chest pain or a heartbeat that is fast or not regular
- Fever or fatigue (mentally and physically tired)
- Joint pain
Call your local emergency number (911 in the US) if:

Treatment
may include any of the following:

Prevent rheumatic fever:
Rheumatic fever is not contagious, but GAS bacteria can be passed from one person to another. The following can help prevent rheumatic fever by preventing the bacteria from spreading:
- Always have strep throat, scarlet fever, or impetigo fully treated. Rheumatic fever can develop again, even after treatment. Take your child in to be tested for a GAS infection as soon as symptoms develop. Your child will need antibiotics to treat the infection. It is important to give every dose, even if your child feels better sooner.
- Wash your hands and your child's hands often. Teach your child to use soap and water. Wash for at least 20 seconds. Rinse with warm, running water for several seconds. Then have your child dry with a clean towel or paper towel. Children older than 2 years may use hand sanitizer that contains alcohol if soap and water are not available.
- Teach your child to cover a sneeze or cough. Have your child turn away from others and cover his or her mouth or nose with a tissue. Your child can use the bend of the arm if a tissue is not available. Then have your child wash his or her hands well with soap and water or use hand sanitizer. Your child should also turn and cover if someone nearby has to sneeze or cough.
- Have your child stay home when he or she is sick. Your child should not go to daycare, school, or work until his or her provider says it is okay. This is usually at least 24 hours after antibiotics are started. Your child will also need to have no fever for 24 hours without fever medicine.
- Clean wounds to prevent an infection. Wash your hands before and after you care for a wound. Clean the area with soap and water. Dry around the wound with a clean towel or paper towel. Put antibiotic cream or gel on the wound to prevent a bacterial infection. Cover the wound with a bandage. Change the bandage each day, and if it gets wet or dirty. If your child has impetigo, follow directions from healthcare providers for cleaning and covering the sores.
